Code P0463 Fuel Level Sensor 1 circuit high

[Rolin2004]

Hello, 2012 Ram 1500 Hemi 5.7L. Truck Broke down and gave me a code P0463. After reading the suggestions I went ahead and Bought me a New Fuel Pump out of Amazon cause it was the fastest to arrive. Once I installed the new Fuel pump the truck would start but now the Truck is sputtering. When I put the code reader again now it says Cylinder 1 misfire. What is wrong with my truck? Some websites says pump may not be pumping enough some says fuel pump relay. Please Help!

Hello, just going to throw some **** against wall on this one.
I would check the fuel pressure under the hood to see if it’s good. The misfire might be a bad fuel injector. Swap two fuel injectors and see if misfire moves to a different cylinder. Sorry, wish I had a better answer.

Also swap two coils to see if the misfire moves. Maybe, just a bad coil.

I did both and still have the same problem. I even replaced all the plugs and the coils.
